Quantum State Engineering with Networks of Optical Parametric Oscillators
Abstract
Networks of optical parametric oscillators (OPOs) provide a fertile ground for generation and studying quantum states of light. These OPO networks are one of the promising platforms for noisy intermediate-scale quantum (NISQ) architectures for computing. In the past few years, PI and collaborators have introduced a semi-classical computing architecture using OPO networks, i.e. the OPO-based Ising machines, have demonstrated a large-scale implementation using the measurement-feedback scheme, and their promising computational performance. Extensive experimental and theoretical research, including in the PIÕs laboratory, is now focused on bringing these scalable nonlinear optical networks to the quantum regime, where the network can realize either entangled Gaussian or non-Gaussian states. These efforts can lead to unprecedented opportunities for NISQ and conventional quantum computing and sensing architectures. This project focuses on combining all-optical OPO networks with single-photon detectors to enable new paths to realization of a large body of non-Gaussian states and studying their behaviors and dynamics for computing and sensing. In parallel to the growing interest in integrated quantum photonics, the hybrid platform of this project promises unprecedented paths for quantum information processing and paves the way to on-demand scalable quantum photonic engineering with OPO networks. The requested equipment, i.e. an 8-channel single-photon detector module, will be used in conjunction with the ongoing experiments with the OPO networks on two experimental platforms, i.e. a table-top platform and an integrated nonlinear photonic platform. Addition of this equipment will significantly enhance and broaden the scope of the DoD-funded project on OPO networks through enabling access to quantum states that are not readily available otherwise and a wealth of experimental opportunities for quantum computing and sensing. The project aims to utilize this additional experimental capability to: (i) experimentally realize and study heralded entangled non-Gaussian states in OPO networks, (ii) experimentally realize and study non-Gaussian states on integrated lithium niobate platform, (iii) and study the quantum topological behaviors and computational consequences of non- Gaussian states in OPO networks and Ising machines.
